➤ Why do people expect accommodation in conversational settings?
People expect accommodation to gain social approval, reduce uncertainty, and improve understanding. Accommodation signals respect and interest and helps manage social identities and power relations. It also eases conversation flow by aligning vocabulary, formality, or nonverbal cues, which increases comfort, efficiency, and the chance of cooperative outcomes.

➤ How do you calculate point price elasticity for a linear demand function step by step?
Differentiate Q with respect to P to get dQ/dP (the slope). Plug into Ep = (dQ/dP)·(P/Q). Evaluate at the chosen price and quantity. For slope = 1, Ep simplifies to P/Q. Remember to keep signs: a downward demand has negative dQ/dP and elasticity will be negative accordingly.

➤ Why do babies use different cries to communicate needs?
Babies cry to signal hunger, pain, discomfort, sleepiness, or frustration. Crying activates caregiver attention and supports feeding and sleep routines. Over time caregivers learn distinct patterns, which strengthens bonding and ensures timely responses to physical needs or illness as the infant’s nervous and social systems develop.
